THE LOCAL ANSWERTake oil-based paint, stain and varnish to the East or Ezell Pike convenience center, Tuesday to Saturday, 8:30 a.m. to 4:30 p.m.; it's free with a Davidson County driver's license. Latex paint isn't accepted. Dry it out with the lid off or with kitty litter, then bag it and put it in your trash.
Nashville splits paint in two. Oil-based paint, stain and varnish go free to Metro's East or Ezell Pike convenience center. Latex paint is not taken there at all: Metro wants you to use it up, give it away, or dry it and put it in your trash.
Only two of the four centers take paint
Metro runs four convenience centers, but hazardous waste goes only to East (943A Doctor Richard G Adams Dr) and Ezell Pike (3254 Ezell Pike). Omohundro and Anderson Lane don't take it. Both are open Tuesday to Saturday, 8:30 a.m. to 4:30 p.m.
Bring a Davidson County license
Staff ask for a Tennessee driver's license with a Davidson County address. Out-of-county residents are turned away, and so is any work truck, van with a business logo, or vehicle with commercial tags.
Water-based stain counts as latex here
Metro's list rejects latex and acrylic paint and also water-based stains. Oil-based stain and varnish are fine. Check the label: "latex", "water-based" or "acrylic" means dry it; "oil based" or "alkyd" means take it to East or Ezell.
Use Metro's one-inch rule for latex
Metro's latex guide says a can with an inch or less will dry with the lid off in a ventilated spot away from kids and pets. More than an inch? Stir in shredded paper, sawdust, mulch, kitty litter or a paint hardener. Bag the dry can and put it in your trash cart.
Monthly cap, not per visit
The free limit is 15 gallons or 100 pounds per household per month, with one hazardous waste visit a day. A large oil-paint cleanout may need trips in two different months.
